Project Status: 3 Approved without Funding
Duration in months: 36 months
Objective
Objective of the project. Organization and implementation of the program of radiation monitoring of contaminated areas and areas with increased radiation background, as well as the study of the migration of radionuclides in the air, soil and water bodies in these areas; development on this basis of effective regional methodology for risks assessment of radiation exposure on human health, practical recommendations to the population regarding reduction of external and internal exposure, correction of radiation safety standards for different groups. The state of affairs in the field of research. Numerous studies of various Kazakhstan scientists have been carried out on separate and uncoordinated monitoring of the local points regarding the radionuclide content separately on objects of the surroundings. These studies are scattered, have the character of statistics gathering, not pursuing the main goal of monitoring – development of practical recommendations to the consumer to improve the radiation environment status based on an integrated approach to the analysis and development of new effective low-cost methods for total monitoring to reduce the radiation risk.
Studies to assess the radiation risk in the North-Kazakhstan region, in the areas with high natural radioactivity the natural earth radionuclides, within the framework of international projects and ISTC projects have not been carried out.
At the moment, a selective radiation monitoring has been carried out on the territories and the analysis was made of the radiation risk of population of some areas in the North-Kazakhstan region bordering with Akmola region (Kazakhstan). Analysis of the available data suggests an increased natural background radiation in the North-Kazakhstan region caused by geological, geochemical, hydrological and anthropogenic factors. The identification is required of regional, individual and collective factors causing radiation, in addition to the background one, as well as set of measures for the prevention of radiation exposure of human body to ionizing radiation above the established norms, the development of practical recommendations to the population regarding reduction of external and internal exposure. The impact of the proposed project on the progress in this field. The research results, methodology of the complex experiments in radiation monitoring and radiation risk will allow to evaluate the presence of correlations between the radiation dose and radiation impact on various population groups of different territories.
The research results of the radiation risk prediction based on multiple-factor system can be recommended to assess the legality of the application of radiation safety standards for specific population groups. On the basis of systematization of a large number of experimental data, a methodology for radiation risk assessment will be developed.
As recommendations for the population and interested organizations to reduce radiation risk the guidelines will be developed and training seminars will be arranged. Expected Results and Their Application. With the use of modern radiation-measuring, physical-chemical and radiochemical methods we expect to get the dynamic characteristics of the radiation status of all environments contacting with the population: drinking water, food, indoor and outdoor air, building materials. The assessment will be given of the impact of the behavior mode, the diet of different ages and professional groups on the level of radiation exposure doses and the extent of individual risk.
The obtained results will allow to determine the places of establishment of the controlled levels and continuous radiation monitoring, to formulate conclusions about the presence of correlations between radiation dose loads and population effects; to evaluate the validity of the application of radiation safety standards for the population of different groups; to develop effective methodical recommendations and to organize training seminars for the public to reduce the extent of the individual radiation risk. Priority routes and potential point of radionuclide exposure of the population of the controlled areas will be identified. Technical Approach and Methodology. The project will use the methodology of the risk assessment recommended by the radiation safety rules, acting in the territory of Kazakhstan and adapted further to international recommendations of the International Radiation Protection Committee.
What is new is the methodological approaches for the collection of regional settings, similar assessment of the health risks from chemical pollutants. It is planned to conduct complex study on the basis of multifactoral system and not used by sanitary-epidemiological services caused by the lack of financing.
